  2. $host = '192.168.0.10';
  3. $port = 88888;
  4. if($socket = socket_create(AF_INET, SOCK_STREAM, SOL_TCP)){
  5. echo " socket create success.n";
  6. }
  7. if($bind = socket_bind($socket, $host, $port)){
  8. echo "socket bind success.n";
  9. }
  10. if($listen = socket_listen( $socket)){
  11. echo "socket listening...n";
  12. }
  13. if($connect = socket_accept($socket)){
  14. echo "socket accept a connect success.n";
